 Subject: gdb-6.5-bz185337-resolve-tls-without-debuginfo-v2.patch
 ;; Support TLS symbols (+`errno' suggestion if no pthread is found) (BZ 185337).
 ;;=push+jan: It should be replaced by Infinity project.
 https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=185337
 2008-02-24  Jan Kratochvil  <jan.kratochvil@redhat.com>
 	Port to GDB-6.8pre.
 currently for trivial nonthreaded helloworld with no debug info up to -ggdb2 you
 will get:
        (gdb) p errno
        [some error]
 * with -ggdb2 and less "errno" in fact does not exist anywhere as it was
  compiled to "(*__errno_location ())" and the macro definition is not present.
  Unfortunately gdb will find the TLS symbol and it will try to access it but
  as the program has been compiled without -lpthread the TLS base register
  (%gs on i386) is not setup and it will result in:
        Cannot access memory at address 0x8
 Attached suggestion patch how to deal with the most common "errno" symbol
 for the most common under-ggdb3 compiled programs.
 Original patch hooked into target_translate_tls_address.  But its inferior
 call invalidates `struct frame *' in the callers - RH BZ 690908.

 From FEDORA_PATCHES Mon Sep 17 00:00:00 2001
 From: Jan Kratochvil <jan.kratochvil@redhat.com>
 Date: Fri, 27 Oct 2017 21:07:50 +0200
 Subject: gdb-6.5-sharedlibrary-path.patch
 ;; Fix TLS symbols resolving for shared libraries with a relative pathname.
 ;; The testsuite needs `gdb-6.5-tls-of-separate-debuginfo.patch'.
 ;;=fedoratest: One should recheck if it is really fixed upstream.
 If you provided some relative path to the shared library, such as with
 	export LD_LIBRARY_PATH=.
 then gdb would fail to match the shared library name during the TLS lookup.
 Dropped the workaround/fix for gdb-6.8.50.20081128 - is it still needed?
 The testsuite needs `gdb-6.3-bz146810-solib_absolute_prefix_is_empty.patch'.
 The testsuite needs `gdb-6.5-tls-of-separate-debuginfo.patch'.
 2006-09-01  Jan Kratochvil  <jan.kratochvil@redhat.com>
 	* solib-svr4.c (svr4_fetch_objfile_link_map): Match even absolute
 	requested pathnames to the internal loaded relative pathnames.
 2007-10-16  Jan Kratochvil  <jan.kratochvil@redhat.com>
 	Port to GDB-6.7.
 2008-02-27  Jan Kratochvil  <jan.kratochvil@redhat.com>
 	Port to gdb-6.7.50.20080227.

 gdb-6.6-buildid-locate-misleading-warning-missing-debuginfo-rhbz981154.patch
 ;; Fix 'gdb gives highly misleading error when debuginfo pkg is present,
 ;; but not corresponding binary pkg' (RH BZ 981154).
 ;;=push+jan
 Comments by Sergio Durigan Junior <sergiodj@redhat.com>:
  This is the fix for RH BZ #981154
  It is mainly a testcase addition, but a minor fix in the gdb/build-id.c
  file was also needed.
  gdb/build-id.c was added by:
  commit dc294be54c96414035eed7d53dafdea0a6f31a72
  Author: Tom Tromey <tromey@redhat.com>
  Date:   Tue Oct 8 19:56:15 2013 +0000
  and had a little thinko there.  The variable 'filename' needs to be set to
  NULL after it is free'd, otherwise the code below thinks that it is still
  valid and doesn't print the necessary warning ("Try: yum install ...").

 Subject: gdb-dont-overwrite-fsgsbase-m32.patch
 ;; Backport "[gdb/server] Don't overwrite fs/gs_base with -m32"
 ;; (Tom de Vries)
 Consider a minimal test-case test.c:
 ...
 int main (void) { return 0; }
 ...
 compiled with -m32:
 ...
 $ gcc test.c -m32
 ...
 When running the exec using gdbserver on openSUSE Factory (currently running a
 linux kernel version 5.10.5):
 ...
 $ gdbserver localhost:12345 a.out
 ...
 to which we connect in a gdb session, we run into a segfault in the inferior:
 ...
 $ gdb -batch -q -ex "target remote localhost:12345" -ex continue
 Program received signal SIGSEGV, Segmentation fault.
 0xf7dd8bd2 in init_cacheinfo () at ../sysdeps/x86/cacheinfo.c:761
 ...
 The segfault is caused by gdbserver overwriting $gs_base with 0 using
 PTRACE_SETREGS.  After it is overwritten, the next use of $gs in the inferior
 will trigger the segfault.
 Before linux kernel version 5.9, the value used by PTRACE_SETREGS for $gs_base
 was ignored, but starting version 5.9, the linux kernel has support for
 intel architecture extension FSGSBASE, which allows users to modify $gs_base,
 and consequently PTRACE_SETREGS can no longer ignore the $gs_base value.
 The overwrite of $gs_base with 0 is done by a memset in x86_fill_gregset,
 which was added in commit 9e0aa64f551 "Fix gdbserver qGetTLSAddr for
 x86_64 -m32".  The memset intends to zero-extend 32-bit registers that are
 tracked in the regcache to 64-bit when writing them into the PTRACE_SETREGS
 data argument.  But in addition, it overwrites other registers that are
 not tracked in the regcache, such as $gs_base.
 Fix the segfault by redoing the fix from commit 9e0aa64f551 in minimal form.
 Tested on x86_64-linux:
 - openSUSE Leap 15.2 (using kernel version 5.3.18):
  - native
  - gdbserver -m32
  - -m32
 - openSUSE Factory (using kernel version 5.10.5):
  - native
  - m32
 gdbserver/ChangeLog:
 2021-01-20  Tom de Vries  <tdevries@suse.de>
 	* linux-x86-low.cc (collect_register_i386): New function.
 	(x86_fill_gregset):  Remove memset.  Use collect_register_i386.

 ;; (Simon Marchi)
 I'm trying to switch these functions to use std::string instead of char
 arrays, as much as possible.  Some callers benefit from it (can avoid
 doing a copy of the result), while others suffer (have to make one more
 copy).

 ;; Backport "gdbsupport: add path_join function"
 ;; (Simon Marchi)
 In this review [1], Eli pointed out that we should be careful when
 concatenating file names to avoid duplicated slashes.  On Windows, a
 double slash at the beginning of a file path has a special meaning.  So
 naively concatenating "/"  and "foo/bar" would give "//foo/bar", which
 would not give the desired results.  We already have a few spots doing:
  if (first_path ends with a slash)
    path = first_path + second_path
  else
    path = first_path + slash + second_path
 In general, I think it's nice to avoid superfluous slashes in file
 paths, since they might end up visible to the user and look a bit
 unprofessional.
 Introduce the path_join function that can be used to join multiple path
 components together (along with unit tests).
 I initially wanted to make it possible to join two absolute paths, to
 support the use case of prepending a sysroot path to a target file path,
 or the prepending the debug-file-directory to a target file path.  But
 the code in solib_find_1 shows that it is more complex than this anyway
 (for example, when the right hand side is a Windows path with a drive
 letter).  So I don't think we need to support that case in path_join.
 That also keeps the implementation simpler.
 Change a few spots to use path_join to show how it can be used.  I
 believe that all the spots I changed are guarded by some checks that
 ensure the right hand side operand is not an absolute path.
 Regression-tested on Ubuntu 18.04.  Built-tested on Windows, and I also
 ran the new unit-test there.

 ;; Backport "Fix undefined behaviour dereferencing empty string"
 ;; (Magne Hov, RHEL-17631)
 When a source file's dirname is solely made up of directory separators
 we end up trying to dereference the last character of an empty string
 with std::string::back, which results in undefined behaviour. A typical
 use case where this can happen is when the root directory "/" is used as
 a compilation directory.
 With libstdc++.so.6.0.28 we get no out-of-bounds checks and the byte
 preceding the storage of the empty string is returned. The character
 value of this byte depends on heap implementation and usage, but when
 this byte happens to hold the value of the directory separator character
 we go on to call std::string::pop_back on the empty string which results
 in an out_of_range exception which terminates GDB.
 Fix this by using path_join. prepare_path_for_appending ensures that the
 filename component is relative.
 The testsuite has been run before and after the change and no
 regressions were found.

 The problem is this line in path_join:
    gdb_assert (strlen (path) == 0 || !IS_ABSOLUTE_PATH (path));
 ... where `path` is "x".  IS_ABSOLUTE_PATH eventually calls
 HAS_DRIVE_SPEC_1:
    #define HAS_DRIVE_SPEC_1(dos_based, f)                  \
      ((f)[0] && ((f)[1] == ':') && (dos_based))
 This macro accesses indices 0 and 1 of the input string.  However, `f`
 is a string_view of length 1, so it's incorrect to try to access index
 1.  We know that the string_view's underlying object is a null-terminated
 string, so in practice there's no harm.  But as far as the string_view
 is concerned, index 1 is considered out of bounds.
 This patch makes the easy fix, that is to change the path_join parameter
 from a vector of to a vector of `const char *`.  Another solution would
 be to introduce a non-standard gdb::cstring_view class, which would be a
 view over a null-terminated string.  With that class, it would be
 correct to access index 1, it would yield the NUL character.  If there
 is interest in having this class (it has been mentioned a few times in
 the past) I can do it and use it here.
 This was found by running tests such as gdb.ada/arrayidx.exp, which
 produce 1-char long filenames, so adding a new test is not necessary.

 ;; Backport "[gdb/testsuite] Fix PR20630 regression test in gdb.base/printcmds.exp"
 ;; (Tom de Vries)
 On s390x-linux, I run into:
 ...
 (gdb) print {unsigned char}{65}^M
 $749 = 0 '\000'^M
 (gdb) FAIL: gdb.base/printcmds.exp: print {unsigned char}{65}
 ...
 In contrast, on x86_64-linux, we have:
 ...
 (gdb) print {unsigned char}{65}^M
 $749 = 65 'A'^M
 (gdb) PASS: gdb.base/printcmds.exp: print {unsigned char}{65}
 ...
 The first problem here is that the test is supposed to be a regression test
 for PR20630, which can be reproduced (for an unfixed gdb) like this:
 ...
 (gdb) p {unsigned char[]}{0x17}
 gdbtypes.c:4641: internal-error: copy_type: \
  Assertion `TYPE_OBJFILE_OWNED (type)' failed.
 ...
 but it's not due to insufficient quoting (note the dropped '[]').
 That's easy to fix, but after that we have on s390 (big endian):
 ...
 (gdb) print {unsigned char[]}{65}^M
 $749 = ""^M
 ...
 and on x86_64 (little endian):
 ...
 (gdb) print {unsigned char[]}{65}^M
 $749 = "A"^M
 ...
 Fix this by using 0xffffffff, such that in both cases we have:
 ...
 (gdb) print {unsigned char[]}{0xffffffff}^M
 $749 = "\377\377\377\377"^M
 ...
 Tested on x86_64-linux and s390x-linux.

 ;; Backport "adjust gdb.python/flexible-array-member.exp expected pattern"
 ;; (Simon Marchi)
 The `Type.range ()` tests in gdb.python/flexible-array-member.exp pass
 when the test is compiled with gcc 9 or later, but not with gcc 8 or
 earlier:
    $ make check TESTS="gdb.python/flexible-array-member.exp" RUNTESTFLAGS="CC_FOR_TARGET='gcc-8'"
    python print(zs['items'].type.range())^M
    (0, 0)^M
    (gdb) FAIL: gdb.python/flexible-array-member.exp: python print(zs['items'].type.range())
    python print(zso['items'].type.range())^M
    (0, 0)^M
    (gdb) FAIL: gdb.python/flexible-array-member.exp: python print(zso['items'].type.range())
 The value that we get for the upper bound of a flexible array member
 declared with a "0" size is 0 with gcc <= 8 and is -1 for gcc >= 9.
 This is due to different debug info.  For this member, gcc 8 does:
    0x000000d5:   DW_TAG_array_type
                    DW_AT_type [DW_FORM_ref4]       (0x00000034 "int")
                    DW_AT_sibling [DW_FORM_ref4]    (0x000000e4)
    0x000000de:     DW_TAG_subrange_type
                      DW_AT_type [DW_FORM_ref4]     (0x0000002d "long unsigned int")
 For the same type, gcc 9 does:
    0x000000d5:   DW_TAG_array_type
                    DW_AT_type [DW_FORM_ref4]       (0x00000034 "int")
                    DW_AT_sibling [DW_FORM_ref4]    (0x000000e5)
    0x000000de:     DW_TAG_subrange_type
                      DW_AT_type [DW_FORM_ref4]     (0x0000002d "long unsigned int")
                      DW_AT_count [DW_FORM_data1]   (0x00)
 Ideally, GDB would present a consistent and documented value for an
 array member declared with size 0, regardless of how the debug info
 looks like.  But for now, just change the test to accept the two
 values, to get rid of the failure and make the test in sync
 I also realized (by looking at the py-type.exp test) that calling the
 fields method on an array type yields one field representing the "index"
 of the array.  The type of that field is of type range
 (gdb.TYPE_CODE_RANGE).  When calling `.range()` on that range type, it
 yields the same range tuple as when calling `.range()` on the array type
 itself.  For completeness, add some tests to access the range tuple
 through that range type as well.
 gdb/testsuite/ChangeLog:
 	* gdb.python/flexible-array-member.exp: Adjust expected range
 	value for member declared with 0 size.  Test accessing range
 	tuple through range type.

 http://sourceware.org/ml/gdb-patches/2014-07/msg00709.html
 Hi,
 for Fortran it fixes displaying normal strings also in frames/backtraces:
 (gdb) frame
 ->
 The patch is simple and I do not see why it should not be this way.
 For C/C++ TYPE_CODE_STRING is not used.  I am not aware of Pascal but that
 language is currently not really much supported in GDB anyway.
 This was a part of my archer/jankratochvil/vla branch but it is not a part of
 the Intel VLA patchset as it in fact is completely unrelated to "VLA".
 No regressions on {x86_64,x86_64-m32,i686}-fedora22pre-linux-gnu.
 Thanks,
 Jan

   Subject: [PATCH] Fix crash when expanding partial symtabs with
 DW_TAG_imported_unit
 PR gdb/27743 points out a gdb crash when expanding partial symtabs,
 where one of the compilation units uses DW_TAG_imported_unit.
 The bug is that partial_map_expand_apply expects only to be called for
 the outermost psymtab.  However, filename searching doesn't (and
 probably shouldn't) guarantee this.  The fix is to walk upward to find
 the outermost CU.
 A new test case is included.  It is mostly copied from other test
 cases, which really sped up the effort.
 This bug does not occur on trunk.  There,
 psym_map_symtabs_matching_filename is gone, replaced by
 psymbol_functions::expand_symtabs_matching.  When this find a match,
 it calls psymtab_to_symtab, which does this same upward walk.
 Tested on x86-64 Fedora 32.
 I propose checking in this patch on the gdb-10 branch, and just the
 new test case on trunk.

 .TH GSTACK 1 "Feb 15 2008" "Red Hat Linux" "Linux Programmer's Manual"
 .SH NAME
 gstack \- print a stack trace of a running process
 .SH SYNOPSIS
 .B gstack
 pid
 .SH DESCRIPTION
 \f3gstack\f1 attaches to the active process named by the \f3pid\f1 on
 the command line, and prints out an execution stack trace.  If ELF
 symbols exist in the binary (usually the case unless you have run
 strip(1)), then symbolic addresses are printed as well.
 If the process is part of a thread group, then \f3gstack\f1 will print
 out a stack trace for each of the threads in the group.
 .SH SEE ALSO
 nm(1), ptrace(2), gdb(1)

 From FEDORA_PATCHES Mon Sep 17 00:00:00 2001

 Subject: gdb-rhbz-2130624-assert_in_jit_event_handler.patch
 ;; Backport "[gdb/breakpoint] Fix assert in jit_event_handler"
 ;; (Tom de Vries, RHBZ2130624)
 Consider a minimal test-case test.c:
 ...
 int main (void) { return 0; }
 ...
 which we can compile into llvm byte code using clang:
 ...
 $ clang -g -S -emit-llvm --target=x86_64-unknown-unknown-elf test.c
 ...
 and then run using lli, which uses the llvm jit:
 ...
 $ lli test.ll
 ...
 If we run this under gdb, we run into an assert:
 ...
 $ gdb -q -batch -ex run --args /usr/bin/lli test.ll
 Dwarf Error: Cannot not find DIE at 0x18a936e7 \
  [from module libLLVM.so.10-10.0.1-lp152.30.4.x86_64.debug]
 [Thread debugging using libthread_db enabled]
 Using host libthread_db library "/lib64/libthread_db.so.1".
 src/gdb/jit.c:1178: internal-error: \
  void jit_event_handler(gdbarch*, objfile*): \
  Assertion `jiter->jiter_data != nullptr' failed.
 ...
 This is caused by the following.
 When running jit_breakpoint_re_set_internal, we first handle
 libLLVM.so.10.debug, and set a jit breakpoint.
 Next we handle libLLVM.so.10:
 ...
 (gdb) p the_objfile.original_name
 $42 = 0x2494170 "libLLVM.so.10"
 ...
 but the minimal symbols we find are from libLLVM.so.10.debug:
 ...
 (gdb) p reg_symbol.objfile.original_name
 $43 = 0x38e7c50 "libLLVM.so.10-10.0.1-lp152.30.4.x86_64.debug"
 (gdb) p desc_symbol.objfile.original_name
 $44 = 0x38e7c50 "libLLVM.so.10-10.0.1-lp152.30.4.x86_64.debug"
 ...
 and consequently, the objf_data is the one from libLLVM.so.10.debug:
 ...
      jiter_objfile_data *objf_data
        = get_jiter_objfile_data (reg_symbol.objfile);
 ...
 and so we hit this:
 ...
      if (objf_data->cached_code_address == addr)
        continue;
 ...
 and no second jit breakpoint is inserted.
 Subsequently, the jit breakpoint is triggered and handled, but when finding
 the symbol for the breakpoint address we get:
 ...
 (gdb) p jit_bp_sym.objfile.original_name
 $52 = 0x2494170 "libLLVM.so.10"
 ...
 The assert 'jiter->jiter_data != nullptr' triggers because it checks
 libLLVM.so.10 while the one with jiter_data setup is libLLVM.so.10.debug.
 This fixes the assert:
 ...
       jiter_objfile_data *objf_data
 -        = get_jiter_objfile_data (reg_symbol.objfile);
 -        = get_jiter_objfile_data (the_objfile);
 ...
 but consequently we'll have two jit breakpoints, so we also make sure we don't
 set a jit breakpoint on separate debug objects like libLLVM.so.10.debug.
 Tested on x86_64-linux.

 Original message by Tom Tromey:
  <https://sourceware.org/ml/gdb-patches/2012-03/msg00955.html>
  Message-ID: <871uoc1va3.fsf@fleche.redhat.com>
 Comment from Sergio Durigan Junior:
  In order to correctly test this patch, I wrote a testcase based on Jan
  Kratochvil's <gdb/testsuite/gdb.base/gcore-excessive-memory.exp>.  The
  testcase, which can be seen below, tests GDB in order to see if the
  amount of memory being leaked is minimal, as requested in the bugzilla.
  It is hard to define what "minimum" is, so I ran the testcase on all
  supported RHEL architectures and came up with an average.

 Subject: gdb-rhbz1149205-catch-syscall-after-fork-test.patch
 ;; Fix '`catch syscall' doesn't work for parent after `fork' is called'
 ;; (Philippe Waroquiers, RH BZ 1149205).
 ;;=fedoratest
 URL: <https://sourceware.org/ml/gdb-patches/2013-05/msg00364.html>
 Message-ID: <1368136582.30058.7.camel@soleil>
  From: Philippe Waroquiers <philippe dot waroquiers at skynet dot be>

  Subject: RFA: fix gdb_assert caused by 'catch signal ...' and fork
  Date: Thu, 09 May 2013 23:56:22 +0200
  The attached patch fixes a gdb_assert caused by the combination of catch
  signal and fork:
    break-catch-sig.c:152: internal-error: signal_catchpoint_remove_location: Assertion `signal_catch_counts[iter] > 0' failed.
  The problem is that the signal_catch_counts is decremented by detach_breakpoints.
  The fix consists in not detaching breakpoint locations of type bp_loc_other.
  The patch introduces a new test.
 Comments by Sergio Durigan Junior:
  I addded a specific testcase for this patch, which tests exactly the
  issue that the customer is facing.  This patch does not solve the
  whole problem of catching a syscall and forking (for more details,
  see <https://sourceware.org/bugzilla/show_bug.cgi?id=13457>,
  specifically comment #3), but it solves the issue reported by the
  customer.
  I also removed the original testcase of this patch, because it
  relied on "catch signal", which is a command that is not implemented
  in this version of GDB.

 Date: Fri, 27 Oct 2017 21:07:50 +0200
 Subject: gdb-rhbz1186476-internal-error-unqualified-name-re-set-test.patch
 ;; Fix 'backport GDB 7.4 fix to RHEL 6.6 GDB' [Original Sourceware bug
 ;; description: 'C++ (and objc): Internal error on unqualified name
 ;; re-set', PR 11657] (RH BZ 1186476).
 ;;=fedoratest
 Comments from Sergio Durigan Junior:
  The "proper" fix for this whole problem would be to backport the
  "ambiguous linespec" patch series.  However, it is really not
  recommended to do that for RHEL GDB, because the patch series is too
  big and could introduce unwanted regressions.  Instead, what we
  chose to do was to replace the gdb_assert call by a warning (which
  allows the user to continue the debugging session), and tell the
  user that, although more than one location was found for his/her
  breakpoint, only one will be used.

    [PATCH, rs6000, v3][PR gdb/27525] displaced stepping across addpcis/lnia.
      This addresses PR gdb/27525.     The lnia and other variations
    of the addpcis instruction write the value of the NIA into a target register.
    If we are single-stepping across a breakpoint, the instruction is executed
    from a displaced location, and thusly the written value of the PC/NIA
    will be incorrect.   The changes here will measure the displacement
    offset, and adjust the target register value to compensate.

    gdb/ChangeLog:
            * rs6000-tdep.c (ppc_displaced_step_fixup): Update to handle
            the addpcis/lnia instruction.

   Author: Will Schmidt <will_schmidt@vnet.ibm.com>
   Date:   Mon Apr 12 14:11:02 2021 -0500
    [PATCH] gdb-power10-single-step
    Hi,
      This is based on a patch originally written by Alan Modra.
    Powerpc / Power10 ISA 3.1 adds prefixed instructions, which
    are 8 bytes in length.  This is in contrast to powerpc previously
    always having 4 byte instruction length.  This patch implements
    changes to allow GDB to better detect prefixed instructions, and
    handle single stepping across the 8 byte instructions.
    Added #defines to help test for PNOP and prefix instructions.
    Update ppc_displaced_step_copy_insn() to handle pnop and prefixed
    instructions whem R=0 (non-pc-relative).
    Updated ppc_displaced_step_fixup() to properly handle the offset
    value matching the current instruction size
    Updated the for-loop within ppc_deal_with_atomic_sequence() to
    count instructions properly in case we have a mix of 4-byte and
    8-byte instructions within the atomic_sequence_length.
    Added testcase and harness to exercise pc-relative load/store
    instructions with R=0.

            gdb/ChangeLog:
            * rs6000-tdep.c:  Add support for single-stepping of
            prefixed instructions.
            gdb/testsuite/ChangeLog:
            * gdb.arch/powerpc-plxv-nonrel.s:  Testcase using
            non-relative plxv instructions.
            * gdb.arch/powerpc-plxv-nonrel.exp: Testcase harness.

    When GDB loads an ELF file, it will warn when a section is not located
    in an ELF segment:

    [snip]
    This has feature has also been reported by various users, most notably
    the Fedora-EOL'd bug 1553086.
    Mark Wielaard explains the issue quite nicely in
       https://sourceware.org/bugzilla/show_bug.cgi?id=24717#c2
    The short of it is, the ELF program headers for debuginfo files are
    not suited to this particular use case. Consequently, the warning
    generated above really is useless and should be ignored.
    This patch follows the same heuristic that BFD itself uses.

 gdb/s390: Correct recording of "store on condition" insns
 The "store on condition" instructions STOC, STOCG, and STOCFH are recorded
 as if their instruction formats resembled that of STG.  This is wrong,
 usually resulting in "failed to record execution log" errors when trying
 to record code with any of these instructions.
 This patch fixes the recording of these instructions.

 Subject: gdb-rhbz1909902-frame_id_p-assert-1.patch
 ;; Backport fix for frame_id_p assertion failure (RH BZ 1909902).
 Make scoped_restore_current_thread's cdtors exception free (RFC)
 If the remote target closes while we're reading registers/memory for
 restoring the selected frame in scoped_restore_current_thread's dtor,
 the corresponding TARGET_CLOSE_ERROR error is swallowed by the
 scoped_restore_current_thread's dtor, because letting exceptions
 escape from a dtor is bad.  It isn't great to lose that errors like
 that, though.  I've been thinking about how to avoid it, and I came up
 with this patch.
 The idea here is to make scoped_restore_current_thread's dtor do as
 little as possible, to avoid any work that might throw in the first
 place.  And to do that, instead of having the dtor call
 restore_selected_frame, which re-finds the previously selected frame,
 just record the frame_id/level of the desired selected frame, and have
 get_selected_frame find the frame the next time it is called.  In
 effect, this implements most of Cagney's suggestion, here:
  /* On demand, create the selected frame and then return it.  If the
     selected frame can not be created, this function prints then throws
     an error.  When MESSAGE is non-NULL, use it for the error message,
     otherwize use a generic error message.  */
  /* FIXME: cagney/2002-11-28: At present, when there is no selected
     frame, this function always returns the current (inner most) frame.
     It should instead, when a thread has previously had its frame
     selected (but not resumed) and the frame cache invalidated, find
     and then return that thread's previously selected frame.  */
  extern struct frame_info *get_selected_frame (const char *message);
 The only thing missing to fully implement that would be to make
 reinit_frame_cache just clear selected_frame instead of calling
 select_frame(NULL), and the call select_frame(NULL) explicitly in the
 places where we really wanted reinit_frame_cache to go back to the
 current frame too.  That can done separately, though, I'm not
 proposing to do that in this patch.
 Note that this patch renames restore_selected_frame to
 lookup_selected_frame, and adds a new restore_selected_frame function
 that doesn't throw, to be paired with the also-new save_selected_frame
 function.
 There's a restore_selected_frame function in infrun.c that I think can
 be replaced by the new one in frame.c.
 Also done in this patch is make the get_selected_frame's parameter be
 optional, so that we don't have to pass down nullptr explicitly all
 over the place.
 lookup_selected_frame should really move from thread.c to frame.c, but
 I didn't do that here, just to avoid churn in the patch while it
 collects comments.  I did make it extern and declared it in frame.h
 already, preparing for the move.  I will do the move as a follow up
 patch if people agree with this approach.
 Incidentally, this patch alone would fix the crashes fixed by the
 previous patches in the series, because with this,
 scoped_restore_current_thread's constructor doesn't throw either.
 gdb/ChangeLog:
 	* blockframe.c (block_innermost_frame): Use get_selected_frame.
 	* frame.c

 	Use save_selected_frame.  Save language as well.
 	(scoped_restore_selected_frame::~scoped_restore_selected_frame):
 	Use restore_selected_frame, and restore language as well.
 	(selected_frame_id, selected_frame_level): New.
 	(selected_frame): Update comments.
 	(save_selected_frame, restore_selected_frame): New.
 	(get_selected_frame): Use lookup_selected_frame.

 	get_selected_frame.
 	* thread.c (restore_selected_frame): Rename to ...
 	(lookup_selected_frame): ... this and make extern.  Select the
 	current frame if the frame level is -1.

 From FEDORA_PATCHES Mon Sep 17 00:00:00 2001

 Subject: gdb-rhbz1909902-frame_id_p-assert-2.patch
 ;; Backport patch #2 which fixes a frame_id_p assertion failure (RH BZ 1909902).
 Fix frame cycle detection
 The recent commit to make scoped_restore_current_thread's cdtors
 exception free regressed gdb.base/eh_return.exp:
  Breakpoint 1, 0x00000000004012bb in eh2 (gdb/frame.c:641: internal-error: frame_id get_frame_id(frame_info*): Assertion `stashed' failed.
  A problem internal to GDB has been detected,
  further debugging may prove unreliable.
  Quit this debugging session? (y or n) FAIL: gdb.base/eh_return.exp: hit breakpoint (GDB internal error)
 That testcase uses __builtin_eh_return and, before the regression, the
 backtrace at eh2 looked like this:
 (gdb) bt
 #0  0x00000000004006eb in eh2 (p=0x4006ec <continuation>) at src/gdb/testsuite/gdb.base/eh_return.c:54
 Backtrace stopped: previous frame identical to this frame (corrupt stack?)
 That "previous frame identical to this frame" is caught by the cycle
 detection based on frame id.
 The assertion failing is this one:
 638           /* Since this is the first frame in the chain, this should
 639              always succeed.  */
 640           bool stashed = frame_stash_add (fi);
 641           gdb_assert (stashed);

 Before the commit to make scoped_restore_current_thread's cdtors
 exception free, scoped_restore_current_thread's dtor would call
 get_frame_id on the selected frame, and we use
 scoped_restore_current_thread pervasively.  That had the side effect
 of stashing the frame id of frame #0 before reaching the path shown in
 the backtrace.  I.e., the frame id of frame #0 happened to be stashed
 before the frame id of frame #1.  But that was by chance, not by
 design.
 This commit:
  commit 256ae5dbc73d1348850f86ee77a0dc3b04bc7cc0
  Author:     Kevin Buettner <kevinb@redhat.com>
  AuthorDate: Mon Oct 31 12:47:42 2016 -0700
      Stash frame id of current frame before stashing frame id for previous frame
 Fixed a similar problem, by making sure get_prev_frame computes the
 frame id of the current frame before unwinding the previous frame, so
 that the cycle detection works properly.  That fix misses the scenario
 we're now running against, because if you notice, the backtrace above
 shows that frame #4 calls get_prev_frame_always, not get_prev_frame.
 I.e., nothing is calling get_frame_id on the current frame.
 The fix here is to move Kevin's fix down from get_prev_frame to
 get_prev_frame_always.  Or actually, a bit further down to
 get_prev_frame_always_1 -- note that inline_frame_this_id calls
 get_prev_frame_always, so we need to be careful to avoid recursion in
 that scenario.
 gdb/ChangeLog:
 	* frame.c (get_prev_frame): Move get_frame_id call from here ...
 	(get_prev_frame_always_1): ... to here.
 	* inline-frame.c (inline_frame_this_id): Mention
 	get_prev_frame_always_1 in comment.

 ;; Backport fix for libstdc++ assert when performing tab completion
 ;; (RH BZ 1912985).
 Fix completion related libstdc++ assert when using -D_GLIBCXX_DEBUG
 This commit fixes a libstdc++ assertion failure encountered when
 running gdb.base/completion.exp.  In order to see this problem,
 GDB must be built with the follow CFLAGS and CXXFLAGS as part
 of the configure line:
  CFLAGS='-D_GLIBCXX_DEBUG' CXXFLAGS='-D_GLIBCXX_DEBUG'
 (Also, this problem was encountered using Fedora rawhide.  It might
 not be reproducible in Fedora versions prior to Fedora 34.)
 Using the gdb.base/completion.exp test program, the problem can be
 observed as follows:

 ;; Backport "Save/restore file offset while reading notes in core file"
 ;; (Keith Seitz, RHBZ 1931344)
 A recent bug (RH BZ 1931344) has exposed a bug in the core file
 build-ID support that I introduced a while ago. It is pretty
 easy to demonstate the problem following a simplified procedure
 outlined in that bug:
 [shell1]
 shell1$ /usr/libexec/qemu-kvm
 [shell2]
 shell2$ pkill -SEGV -x qemu-kvm
 [shell1]
 Segmentation fault (core dumped)
 Load this core file into GDB without specifying an executable
 (an unfortunate Fedora/RHEL-ism), and GDB will inform the user
 to install debuginfo for the "missing" executable:
 $ gdb -nx -q core.12345
 ...
 Missing separate debuginfo for the main executable file
 Try: dnf --enablerepo='*debug*' install /usr/lib/debug/.build-id/e2/e9c66d3117fb2bbb5b2be122f04f2664e5df54
 Core was generated by `/usr/libexec/qemu-kvm'.
 Program terminated with signal SIGSEGV, Segmentation fault.
 ...
 The suggested build-ID is actaully for gmp not qemu-kvm. The problem
 lies in _bfd_elf_core_find_build_id, where we loop over program headers
 looking for note segments:
  /* Read in program headers and parse notes.  */
  for (i = 0; i < i_ehdr.e_phnum; ++i, ++i_phdr)
    {
      Elf_External_Phdr x_phdr;
      if (bfd_bread (&x_phdr, sizeof (x_phdr), abfd) != sizeof (x_phdr))
        goto fail;
      elf_swap_phdr_in (abfd, &x_phdr, i_phdr);
      if (i_phdr->p_type == PT_NOTE && i_phdr->p_filesz > 0)
        {
          elf_read_notes (abfd, offset + i_phdr->p_offset,
                          i_phdr->p_filesz, i_phdr->p_align);
          if (abfd->build_id != NULL)
            return TRUE;
        }
 elf_read_notes uses bfd_seek to forward the stream to the location of
 the note segment. When control returns to _bfd_elf_core_fild_build_id,
 the stream is no longer in the location looking at program headers, and
 all subsequent reads will read from the wrong file offset.
 To fix this, this patch marks the stream location and ensures
 that it is restored after elf_read_notes is called.

 Subject: gdb-rhbz1941080-fix-gdbserver-hang.patch
 ;; Backport change which fixes gdbserver testing hang on f34 and rawhide.
 Fix potential hang during gdbserver testing
 We're currently seeing testing of native-extended-gdbserver hang while
 testing the x86_64 architecture on both Fedora 34 and Fedora Rawhide.
 The test responsible for the hang is gdb.threads/fork-plus-threads.exp.
 While there is clearly a problem/bug with this test on F34 and
 Rawhide, it's also the case that testing should not hang.  This commit
 prevents the hang by waiting with the "-nowait" flag in
 close_gdbserver.
 The -nowait flag is also used in the kill_wait_spawned_process proc in
 gdb/testsuite/lib/gdb.exp, so there is precedent for doing this.
 There are also 15 other uses of "wait -i" scattered throughout the
 test suite.  While it's tempting to change these to also use the
 -nowait flag, I think it might be safer to defer doing so until we
 actually see a problem.
 I've tested this patch on Fedora 32, 33, 34, and Rawhide.  Results are
 comparable on Fedora 32 and 33.  On Fedora 34 and Rawhide, with this
 commit in place, testing completes when the target_board is
 native-extended-gdbserver.  On those OSes, when not using this commit,
 testing usually hangs due to a problem with
 gdb.threads/fork-plus-threads.exp.  I've also tested on all of the
 mentioned OSes with target_board=native-gdbserver; for that testing,
 I achieved comparable results over a number of runs.  (Unfortunately
 results are rarely identical due to racy tests.)

 gdb: Convert enum range_type to a bit field enum
 The expression range_type enum represents the following ideas:
  - Lower bound is set to default,
  - Upper bound is set to default,
  - Upper bound is exclusive.
 There are currently 6 entries in the enum to represent the combination
 of all those ideas.
 In a future commit I'd like to add stride information to the range,
 this could in theory appear with any of the existing enum entries, so
 this would take us to 12 enum entries.
 This feels like its getting a little out of hand, so in this commit I
 switch the range_type enum over to being a flags style enum.  There's
 one entry to represent no flags being set, then 3 flags to represent
 the 3 ideas above.  Adding stride information will require adding only
 one more enum flag.
 I've then gone through and updated the code to handle this change.
 There should be no user visible changes after this commit.

 Subject: gdb-rhbz1964167-fortran-array-strides-in-expressions.patch
 ;; [fortran] Backport Andrew Burgess's commit which adds support
 ;; for array strides in expressions.
 gdb/fortran: add support for parsing array strides in expressions
 With this commit GDB now understands the syntax of Fortran array
 strides, a user can type an expression including an array stride, but
 they will only get an error informing them that array strides are not
 supported.
 This alone is an improvement on what we had before in GDB, better to
 give the user a helpful message that a particular feature is not
 supported than to just claim a syntax error.
 Before:
  (gdb) p array (1:10:2, 2:10:2)
  A syntax error in expression, near `:2, 2:10:2)'.
 Now:
  (gdb) p array (1:10:2, 2:10:2)
  Fortran array strides are not currently supported
 Later commits will allow GDB to handle array strides correctly.
 gdb/ChangeLog:
 	* expprint.c (dump_subexp_body_standard): Print RANGE_HAS_STRIDE.
 	* expression.h (enum range_type): Add RANGE_HAS_STRIDE.
 	* f-exp.y (arglist): Allow for a series of subranges.
 	(subrange): Add cases for subranges with strides.
 	* f-lang.c (value_f90_subarray): Catch use of array strides and
 	throw an error.
 	* parse.c (operator_length_standard): Handle RANGE_HAS_STRIDE.
 gdb/testsuite/ChangeLog:
 	* gdb.fortran/array-slices.exp: Add a new test.

 gdb/fortran: Clean up array/string expression evaluation
 This commit is a refactor of part of the Fortran array and string
 handling code.
 The current code is split into two blocks, linked, weirdly, with a
 goto.  After this commit all the code is moved to its own function,
 and arrays and strings are now handled using the same code; this will
 be useful later when I want to add array stride support where strings
 will want to be treated just like arrays, but is a good clean up even
 without the array stride work, which is why I'm merging it now.
 For now the new function is added as a static within eval.c, even
 though the function is Fortran only.  A following commit will remove
 some of the Fortran specific code from eval.c into one of the Fortran
 specific files, including this new function.
 There should be no user visible changes after this commit.
 gdb/ChangeLog:
 	* eval.c (fortran_value_subarray): New function, content is taken
 	from...
 	(evaluate_subexp_standard): ...here, in two places.  Now arrays
 	and strings both call the new function.
 	(calc_f77_array_dims): Add header comment, handle strings.

 gdb: rename 'enum range_type' to 'enum range_flag'
 To avoid confusion with other parts of GDB relating to types and
 ranges, rename this enum to make it clearer that it is a set of
 individual flags rather than an enumeration of different types of
 range.
 There should be no user visible changes after this commit.
 gdb/ChangeLog:
 	* expprint.c (print_subexp_standard): Change enum range_type to
 	range_flag and rename variables to match.
 	(dump_subexp_body_standard): Likewise.
 	* expression.h (enum range_type): Rename to...
 	(enum range_flag): ...this.
 	(range_types): Rename to...
 	(range_flags): ...this.
 	* f-lang.c (value_f90_subarray): Change enum range_type to
 	range_flag and rename variables to match.
 	* parse.c (operator_length_standard): Likewise.
 	* rust-exp.y (rust_parser::convert_ast_to_expression): Change enum
 	range_type to range_flag.
 	* rust-lang.c (rust_evaluate_funcall): Likewise.
 	(rust_range): Likewise.
 	(rust_compute_range): Likewise.
 	(rust_subscript): Likewise.

 ;; [fortran] Backport Andrew Burgess's commit which eliminates undesirable

 gdb/fortran: Change whitespace when printing arrays
 This commit makes the whitespace usage when printing Fortran arrays
 more consistent, and more inline with how we print C arrays.
 Currently a 2 dimensional Fotran array is printed like this, I find
 the marked whitespace unpleasant:
  (( 1, 2, 3) ( 4, 5, 6) )
    ^          ^        ^
 After this commit the same array is printed like this:
  ((1, 2, 3) (4, 5, 6))
 Which seems more inline with how we print C arrays, in the case of C
 arrays we don't add extra whitespace before the first element.
 gdb/ChangeLog:
 	* f-valprint.c (f77_print_array_1): Adjust printing of whitespace
 	for arrays.

 From FEDORA_PATCHES Mon Sep 17 00:00:00 2001
 From: Kevin Buettner <kevinb@redhat.com>
 Date: Mon, 24 May 2021 17:00:17 -0700
 Subject: gdb-rhbz1964167-move-fortran-expr-handling.patch
 ;; [fortran] Backport Andrew Burgess's commit which moves Fortran
 ;; expression handling to f-lang.c.
 gdb/fortran: Move Fortran expression handling into f-lang.c
 The Fortran specific OP_F77_UNDETERMINED_ARGLIST is currently handled
 in the generic expression handling code.  There's no reason why this
 should be the case, so this commit moves handling of this into Fortran
 specific files.
 There should be no user visible changes after this commit.
 gdb/ChangeLog:
 	* eval.c: Remove 'f-lang.h' include.
 	(value_f90_subarray): Moved to f-lang.c.
 	(eval_call): Renamed to...
 	(evaluate_subexp_do_call): ...this, is no longer static, header
 	comment moved into header file.
 	(evaluate_funcall): Update call to eval_call.
 	(skip_undetermined_arglist): Moved to f-lang.c.
 	(fortran_value_subarray): Likewise.
 	(evaluate_subexp_standard): OP_F77_UNDETERMINED_ARGLIST handling
 	moved to evaluate_subexp_f.
 	(calc_f77_array_dims): Moved to f-lang.c
 	* expprint.c (print_subexp_funcall): New function.
 	(print_subexp_standard): OP_F77_UNDETERMINED_ARGLIST handling
 	moved to print_subexp_f, OP_FUNCALL uses new function.
 	(dump_subexp_body_funcall): New function.
 	(dump_subexp_body_standard): OP_F77_UNDETERMINED_ARGLIST handling
 	moved to dump_subexp_f, OP_FUNCALL uses new function.
 	* expression.h (evaluate_subexp_do_call): Declare.
 	* f-lang.c (value_f90_subarray): Moved from eval.c.
 	(skip_undetermined_arglist): Likewise.
 	(calc_f77_array_dims): Likewise.
 	(fortran_value_subarray): Likewise.
 	(evaluate_subexp_f): Add OP_F77_UNDETERMINED_ARGLIST support.
 	(operator_length_f): Likewise.
 	(print_subexp_f): Likewise.
 	(dump_subexp_body_f): Likewise.
 	* fortran-operator.def (OP_F77_UNDETERMINED_ARGLIST): Move
 	declaration of this operation to here.
 	* parse.c (operator_length_standard): OP_F77_UNDETERMINED_ARGLIST
 	support moved to operator_length_f.
 	* parser-defs.h (dump_subexp_body_funcall): Declare.
 	(print_subexp_funcall): Declare.
 	* std-operator.def (OP_F77_UNDETERMINED_ARGLIST): Moved to
 	fortran-operator.def.
